Diminished Value Claim Utah: The Law, and What Yours Is Worth

You got rear-ended. Insurance paid for repairs. The body shop did great work. Your car looks perfect.

But here is what nobody tells you: the moment that accident shows up on Carfax, your car is permanently worth less. Carfax transaction data shows accident-history vehicles sell for 10–25% less than identical clean-title vehicles. That is not a guess — it is millions of actual dealer transactions.

A 2023 Toyota Camry worth $28,500 before the accident? After repairs, it is worth $24,200 on the open market. That $4,300 gap is diminished value — and in Utah, the at-fault driver's insurance owes it to you.

Most of the calls we turn away fail one of these, so start here before you spend a dollar.

1. Was someone else at fault, and are you claiming against THEIR insurer? Diminished value in Utah is a third-party claim, made against the at-fault driver's liability carrier. Your own collision coverage almost never pays DV — standard Utah policies do not write it in. If the only carrier in the picture is your own, the answer is usually no, and we will say so before you pay for an appraisal.

2. Was the car repaired, and did you keep it? DV measures what your repaired car lost on the open market. If the insurer totaled it, there is no post-repair market to measure — what you have is an actual cash value dispute, a different claim argued a different way.

3. Were you less than 50% at fault? Utah uses modified comparative fault under §78B-5-818. Under 50% and you recover, reduced by your share. At 50% or more, recovery is barred.

Three yeses and you likely have a real claim.

Utah has no diminished value statute. It does not need one — the Utah Supreme Court settled it, twice.

Hill v. Varner, 4 Utah 2d 166, 290 P.2d 448 (1955) is the controlling case: damages for a wrecked vehicle include the cost of repair plus any loss in market value remaining after reasonable repairs. It restated Metcalf v. Mellen, 57 Utah 44, 192 P. 676 (1920), which had said the same thing thirty-five years earlier. So when an adjuster tells you Utah does not recognise diminished value, they are describing a state you do not live in.

Hill is also the best argument for getting a real appraisal. The owner there tried to prove his vehicle's value on his own opinion and nothing else. He recovered five dollars. The law was on his side; his evidence was not.

§78B-2-307(3) gives you four years from the date of loss on a vehicle property damage claim.

§31A-22-304(2)(a)(iii) sets Utah's minimum property damage liability limit at $25,000 for policies issued or renewed on or after January 1, 2025. Most DV claims sit well inside that, so policy limits are rarely the obstacle — the adjuster's offer is.

One caution you will not find in a template article: Utah's unfair-claims rules under R590-190 get quoted at adverse carriers constantly, but the fair-settlement and prompt-payment subsections govern first-party claims — your own insurer's duties to you. Citing them against the other driver's carrier invites a correction that costs you credibility. On a third-party DV claim the authority that works is Hill, backed by a market appraisal the adjuster cannot wave off.

It depends on the vehicle, the severity, and the local market. Real ranges:

• •Typical claim: $3,000–$8,000
• •Luxury vehicles: $10,000–$20,000+
• •Nearly new, under two years: the steepest loss, because accident history bites hardest when the car is otherwise pristine
• •Trucks and SUVs: often above sedans, on higher base values
• •EVs: among the largest claims we see — buyers are especially wary of a damaged battery-era vehicle
• •Structural or frame damage: a tier of its own, because the flag never comes off the record

Expect the insurer to reach for the 17c formula. It came out of a Georgia case, caps the loss at 10% of value, then cuts it again for severity and mileage. It is not Utah law and it is not a market appraisal. We replace it with dealer transaction data and comparable sales — see the full 17c breakdown.

Step 1: Finish the repairs. The DV claim is separate from repair cost and is made after the work is done.

Step 2: Get a certified appraisal. A USPAP-compliant diminished value appraisal documents before-and-after market value from real dealer data. This is the evidence Hill v. Varner says you need.

Step 3: Submit a written demand. A package with the appraisal, the comparable sales behind it, and the Utah authority goes to the at-fault carrier.

Step 4: Negotiate, and escalate if they stall. Most claims resolve in 30–60 days. If the carrier will not move, Utah small claims court handles disputes up to $20,000 under §78A-8-102 with no attorney required — which covers the large majority of DV claims. Above that, district court.
